The heavy woven twill side scrubs well, while the fleece side is super absorbent. Made from 10 oz. per yard, 104 thread count per square inch, flannel glove cotton for durability. Strips are 7/8" x 6" for custom cuts to fit specific cleaning needs and are ideal for loop-style tips. Packaged in bags of 100 or 1000 in a variety of calibers.
